Resumen
4.0 industrial revolution gives opportunity for education through learning technology. Mobile learning is the use of technology in the learning process using tablets, PCs or smartphones. Technological development in education is the use of Android which is a medium for mobile learning that is more flexible. Online based mobile learning provides opportunities for students to study anytime and anywhere. This study aims to determine the effectiveness of the use of electronic guide books and electronic-based assessment in a basic physics practicum with reflectance material on a flat mirror. The study involved 65 physics education students with 35 students in the experimental class and 30 students in the control class. This research is true experimental research with the post-test end-experimental control group design. Based on the evaluation, in very good category at the communication?s indicator and classification?s indicator for experimental class, and in very good category at the compiles the data table?s indicator, for control class.
